High Voltage Power Supply Circuit

A button is utilized as a push-to-talk switch. While it generally functions correctly, there is a significant delay of approximately five seconds before any audio output is heard upon pressing the button. The described circuit involves a push-to-talk switch, which...

This circuit emits a loud tone if the input switch (S2) is not retriggered at designated intervals. If the user falls asleep and fails to re-trigger the circuit, it will continue to sound until S2 is pressed. The circuit operates...

These short-circuit protected regulators provide output voltages of 6, 7, and 9 V from a nominal automobile battery supply of 13 V. They are also compatible with smoothed DC outputs from transformer/rectifier circuits. Two configurations are designed for both...

The simplified block diagram of a high-sensitivity alarm circuit features a photoresistor (LDR) and three ordinary resistors connected in a specific configuration. When transitioning from complete darkness to full light, the potential at point X varies between approximately 1/4...

As is commonly the case, this supply was born of necessity. There is absolutely nothing special about the circuit, except that as shown, it is quite capable of up to 20 Amps intermittently or 10A continuous. Simply use a...

A circuit for monitoring supply voltages of ±5 V and ±12 V can be constructed as shown in the diagram. It is significantly simpler than the typical monitors that utilize comparators and AND gates. The circuit is not designed...
